Impossible d'installer miniconda3 sur un mac

je suis en train d'installer miniconda via le script bash de l'officiel source. J'ai suivi toutes les instructions officielles ainsi que vérifié deux fois avec les informations existantes pour l'installation de miniconda 3 via bash.

je reçois cette erreur sur les paramètres régionaux;

Mes paramètres régionaux par défaut est définie à export LC_ALL="en_US.UTF-8"export PATH="/usr/local/sbin:$PATH" si ça peut aider.

Voici mon contenu bash_profile:

test -e "${HOME}/.iterm2_shell_integration.bash" && source "${HOME}/.iterm2_shell_integration.bash"

export LANG="en_US.UTF-8"

export LC_ALL="en_US.UTF-8"export PATH="/usr/local/sbin:$PATH"


export PATH="/usr/local/sbin:$PATH"

voici ma localisation paramètres:

LANG="en_US.UTF-8"
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
